Set-Up & Operation
- Heating & Stirring
Optimising the temperature performance of your StarFish
The heating performance of your StarFish will be affected by:
1. The limit of the maximum operating temperature of the stirring hotplate.
2. Heating power (Watts) of the stirring hotplate.
3. Flatness of the top plate on the stirring hotplate.
4. Ambient temperature.
5. Load to be heated.
6. Maximum housing temperature of the stirring hotplate.
7. Whether you use a separate temperature controller (probe) see overleaf.

Warning
When placing oil baths, sand baths or aluminium blocks etc onto a stirring hotplate the increased surface area will reflect
heat back to the stirring hotplate. In such instances care should be taken to ensure that the hotplates external housing
does not exceed the maximum temperature recommended by the manufacturer. Such overheating can cause damage to
internal and/or external parts and lead to failure of your stirring hotplate.
!
Warning
Always refer to the manufacturers operating instructions for your stirring hotplate before using it with the StarFish to be
sure of any limitations or safety restrictions.
!
Using a separate temperature controller
For accurate temperature control of your block and/or solution temperature we recommend
using a temperature controller such as the Hei-Con Temperature Sensor V2A
(509-88000-00).
All StarFish blocks feature a hole (3.5mm ID) for inserting a temperature probe.
Warning
Temperature controller wire/cable should not contact with the heated base
of the StarFish. Always rotate the StarFish base to ensure that the probe
hole is nearest the probe socket on the stirring hotplate.
!
Important Note
Please note that typically temperature controllers should be set between
5˚C and 15˚C above the boiling point of the solvent to achieve
a gentle reflux.
